(ci. ca -sai) Claims.

This invention relates toan improved method and apparatus for packaging asphalt and an improved package or container therefor. Under the ordinary methods of manufacturing asphalt and using the same, the asphalt is prepared at a manufacturing plant in suitable stills or furnaces and is then placed in containers or packages of various sizes to await purchase by consumers. Asphalt in this condition is almost a solid, although it is capable of some movement having some fluidity. The containers in most instances are of a standard size adapted to hold 100 pounds, 200 pounds or 400 pounds. Smaller and larger containers within reasonable limits can also be provided, if desired.

Various formssof containers have come into general use in `the trade.' Cylindrical metal drums or containers are one type. Others include paper bags or rectangular fiber or cardboard boxes. The metallic drums must be opened and the contents removed from an open end or the drum must be demolished to remove the asphalt. Paper bags land boxes are, of course, destroyed in removing the asphalt.

Metallic containers are most expensive and naturally increase the cost of asphalt to the consumer. Paper bags and boxes are not satisfactory under certain conditions. tear easily and expose the asphalt to a-certain amount of deterioration. 'I'he boxesv must be firmly built and closed and this involves time consumed and the expense of the materials. Of the types of containers now in use metallic drums or containers are the most preferable but the expense of the same limits their use.

One of the objects of this invention is to provide an improved cylindrical drum or container for asphalt.

A further object is to provide a method of constructing cylindrical containers of the type described wherein the cylinder comprises a body portion and two end or cap portions and the same is assembled by sewing or stitching with metal or other thread.

A further object of the invention is to provide improved apparatus for manufacturing the cylindrical containers mentioned.

The bags l v A further object of the invention is to provide an improved drum or container constructed Aof a paper or card-board material which is .sum-v ciently rigid to provide a good package during shipment or storage, but which can be easily destroyed when it is desired to use the asphalt therein. I

A further object of the invention is to provide an improved drum or cylindrical container constructed of a paper or card-board material and havingy means associated therewith for easily splitting or tearing the drum or containerl so that the asphalt can be removed.

A further object is to provide an improved drum or cylindrical container of the type described constructed lof a paper or card-board v that has previously been treated upon its inmay be ielescopically mounted kwithin the upper Other objects and advantages will be moreA apparent from the following description wherein reference is had to the accompanying three sheets of drawings upon which- Figure 1 is a front perspective view of one of the containers constructed in accordance with my invention.

Figure 2 is an enlarged fragmentary sectional view showing the package mutiiating cord and is taken on the lines 2-2 of Figure 1.

Figure 3 is an enlarged fragmentary side view showing the manner in which the overlapped sides of the container body are fastened together.

Figure 4 is a front perspective view of a modifled construction of cylindrical container showing the manner in which the case is constructed with ordinary stitching of the seams.

Figure 5 is a side elevational view of a stitching machine and container assembling mechanism.

Figure 6 is a fragmentary cross sectional view.

through the same taken generally on the lines 6-6 of Figure 5.

Figure 7 is a plan view of the container holding mechanism used in constructing the same.

In the embodiment of the invention which I have chosen to illustrate, in Fig. 1 I have shown a cylindrical container I 0 which is constructed in accordance with my invention. The container itself comprises the cylindrical shell I2v which is formed of a rectangular sheet of paper that has its edges Il and. I6 folded over and fastened together by a plurality of staples. A bottom cap i8 is provided with a' downwardly turned edge 20 which in turn is fastened by a plurality of staples 22 around the lower edge of the body I2 of the container. An upp'er cap- 2l of the usual type familiar of wire guide members 58. The

cylindrical end of the container and be heldin position either by 'friction or by staples if desircd. The container thus ydescribed is constructed of a comparatively thin cardboard and Y comprises three elements: a rectangular sheet from which the cylindrical body is formed, and the lower and upper cap or closure members which maybe constructed from a similar matainer and extend the height of the same. The

member may also extend around the periphery of the container adjacent the base as shown at Il.l The cord 26 may be fastened securely in position adjacent to the upper and lower ends of the container by a pair of staples 28 and 38. As.

thus constructed, it can be Seen that a comparatively simple container has 4been provided and one which is easily tom open so that the asphalt which. is in the form of a cylinder in the same can easily be removed therefrom and used.

In order to prevent the asphalt from adhering to the interior walls of the cylinder, I have provided a coating upon the interior walls of the same so that the hot asphalt which is owed into the container and hardens does not adhere to the surface. Thus the removal oi the container from the asphalt is easily and simply e'ected. During storage or shipment, the asphalt is protected by the container and is in neat package form so that it can be easily handled and moved about.

` In Figure 4 I have shown a similar cylindrical container lila constructed or similar parts but in which the same are fastened together by either metal or cloth stitching 82 about its edges.

In Figures 5 to 7 I have illustrated generally the method of constructing the containers described and the mechanism for carrying out this operation. Thus in Figure 5 li have shown the usual type of stitching 'mechanism #Il` provided with the base 4/2, the the head 46. The stitching machine 4Z may be in the art, which includes la wire magazine 88, feed mechanism 48, and clincher mechanism 50 positioned above a block or anvil 52 upon which the work that is to be stapled is placed. Sincethis type of stitcher is so well known on the the market no further explanation of the same will be given.

In assembling the container which I have de scribe'd the sheet I2 of paper isplaced within the cylindrical house or hopper 54 over a plurality wire guide members may all be fastened at one end in the end wall 58 of the housing Il and have their opposite ends connected to a col-lar 68. The collar 88 is l slidably mounted upon anaxial rod 82. When a sheet of paper is placed in the housing 54 with its edges Il and I8 overlapping the handle 86,

connected by a link 68 to the collar 80 is moved forward with the I result that the guide wires 58- spread out and press the sheet I2 against the interior vsurface of the housing 5l, thus forming the container body into a cylindrical shape. a. An opening defined by the edges 18 is provided in the upper side of vthe housing 5|.l

The housing 54 may-be carried by a pair of arms 12 connected together by a bracket 14. The

bracket ll may have an axial bore 18 so that it upright standard M, and

to ride below and bearing against a rail 98. TheY rod 18 andthe rails 88 and 88 are supported by suitable bracket members 82 and 94 at their extended ends.

lWith the construction thus far described it can be seen that whena sheet I2 is placed in the member- 54 andfastened in place by guide wires 56, the same may be moved forward below the clincher member 50 of a stitching machine upon the anvil 52 and the staples S previously described may be placed'in position, thus making the open-ended cylindrical body portion of the container. The-end caps may then be placed upon the open-ended cylinder as shown in Figure 2, the cylinder disposed on the anvil 62 with the upper end against the stop member 98 and by rotating the container the staples 22 may be put in position, fastening the end on': the con-` tainer. When it is 'desired to fasten the upper end on the container after it has been iilled with asphalt this may be done with a hand stitching machine or in any other suitablerorV desirable manner; 1

From the above and foregoing .description it will be apparent to those skilled inl the art that I have provided a comparatively simple mechanism for constructing the containers which form the subject matter of this invention. The methods by which the same are constructed are such that they can be carried out by the average unskilled artisan in an asphalt manufacturing plant and the containers can thus be constructed at the factory where the asphalt is!L being made. While I have not shown the construction of a'stitching machine for making the container shown in Fig ure il with continuous stitching instead of with staples itis quite apparent from the construction of the container that the apparatus and method used would be `very similar to that herein shown. The stitching machine, while it might of a different type, would be operated in substantially thesame manner in combination with the-house or form for the cylinders.

From the above and foregoing description it will be apparent to those skilled in the art that I have provided a highly improved container for asphalt which overcomes all of the objections that have been mentioned against the other types of containers known in the art. In addition, I have described a comparatively simple method and apparatus for constructing these'containers so that the same can be assembled and made ready for use as asphalt is being prepared.

While I have illustrated and described a specific embodiment of my invention, it will be apparent to those-.skilled in the art that changes and modifications can be made in the-exact details shown and I dont wish to limit myself United cylindrical container body so that the same may be stapled by said stapling machine.
